H. M. WYETH, OF PULASKI, IOWA.

IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 34,711, dated March 18,1862.

To all whom it may concern:

Be it known that I, H. M. WYETH, of Pulaski, in the count-y of Davis andState of Iowa, have invented a certain new and useful Improvement inPumps; and I do hereby declare the following to be a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, forming a part of this speciiication, and in which- Figure lrepresents a side View of the pump, and Fig. 2 represents a longitudinalsection.

In the accompanying drawings, A represents the piston box or chamber,which is made squareor four-sided. The top B and bottom C are let intothe sides, as indicated in the drawings.

D is the piston-head, which is also square to fit the interior ofchamber or box A, and E is the piston-rod, made fast at the bottom tothe piston-headv D and extending up through the top B to any desiredheight.

The top B has an opening through it to admit water from above when thepiston descende, and a valve a on its under side to close said openingwhen the piston rises. Bottom C has also an opening to admit water whenthe piston rises, and a valve b on its inner side to close said openingwhen the piston descends. When the piston-rodE and piston D rise fromthe position shown in Fig. 2, the upper valve a closes, as seen in thedrawings, and the water escapes or is forced out of opening d, forcingthe long valve e back against the discharge pipe or box F, as indicatedin the drawings, when the water is forced up the channel or way g andout` of the top of pipe F, which is to be made of any convenient height.On the descent of the piston the water below the same, and which enteredthrough valve l) as the piston was elevated, is prevented from passingout at the bottom by the closing of valve b. Consequently it is forcedout of the opening c into the discharge-pipe F, and, rising,

i closes valve c, and continues up and ont of pipe F through the channelor way g.

Pipe F may be made from a scantling or from boards first sawed or splitinto proper widths.

The Yvalve c is so combined with the pumpbox A and pipe F as to answeras a double Valve, as will be readily understood by those skilled in theart from the drawings and the above description.

The constructionof pipe F is very simple, and it can be fastened to theside of the piston-box A by nails or screws.

The piston-box A is made of boards or plank, and the construction ofthis is so simple that it can be constructed with great ease. The sidesof the bottom of boxA are cut out, as seen at h, to allow of the freepassage of the water to the interior when the piston-rod is raised.

The size of box A will be governed by the views of the constructor.

` The position of box A is to be at the bottom of the well or water tobe raised, or at least so far immersed in the water that the top of boxA will be always below the surface of the water, the rod E and pipe Fextending to the proper height, so that the forsingle side valve c withthe pump box or chamber A, and discharge-pipe F, subst-antially as andfor the purposes set forth.

In witness whereof I have hereunto subn scribed by name.
